Precautions

Antihistamines such as carbinoxamine should not be used in newborn or premature infants.

Reports of excitability in children (i.e. < 18 years) receiving carbinoxamine therapy has rarely been reported.

Antihistamines are more likely to cause dizziness, sedation, and hypotension in elderly patients (i.e. >=60 years). Because of its anticholinergic properties, carbinoxamine meets the Beers criteria as a medication that is potentially inappropriate for use in older adults. Nonanticholinergic antihistamines are preferred in elderly patients when treating allergic reactions.

Dialysis

Data not available

Other Comments

Dosage should be titrated individually depending on patient response and severity of symptoms. The lowest effective dosage should be used to minimize sedation and other adverse effects.
